Please, no usb charging on this light
Three things in life are certain.
1. Death
2. Taxes
3. Lumen9000’s relentless crusade for USB charging.
im with yah 
i hate in built usb charge. It’s unreliable and lost of waterproof.

Very convenient.
Do not charge LiIon while sleeping.
Changed your phone’s battery often nowadsyes? Would be ashame if your phone had charging capabilities.
Charging is completely separate from the LED driver. Anduril’s code is irrelevant to this topic.
You participated in the recent poll about built-in charging, so I assume you’re aware of people’s reasons for not wanting it, but there are a bunch of other reasons on top of all the stuff people mentioned in that thread… like engineering, cost, and safety.
Charging a single-cell LiIon-only light isn’t so bad, though it’s still typically not great. NiMH is much more difficult though, and in a light which can take alkaline primaries, lithium primaries, NiMH, NiCD, LiIon, and LiFePO4… even if all the circuitry could fit inside such a small light, the SP10 is primarily sold to non-enthusiasts who may not even know not to charge an alkaline cell. I handled Sofirn’s Amazon returns for a while, and you know what the #1 reason was for returns? Customers couldn’t figure out that they needed to remove the shipping protection stickers from batteries.
This light needs to be safe for that market.
Well said TK.
That’s the curse of knowledge. We know and therefore we don’t know what it’s like to not know these things.
There are li-ion battery charger ICs that will detect a short at a voltage higher than AA cells, including lithium cells, therefore those wouldn’t try to charge primary cells.
There are also nimh/li-ion charger ICs, although the few I’ve seen require an input to choose the chemistry (juste a simple high/low, or I2c), there are probably standalone ones that can detect which chemistry was inserted, but then there is a risk of charging a primary cell.
In any cases there are other considerations, as TK and others have mentionned, but I don’t think the dual chemistry is an issue here, well aside from a customer complaining that the light isn’t recharging his alkaline…
It’d be cool to get some changes done to the host for this light, but Sofirn won’t even change the clip.
The prototype which arrived yesterday was pretty much identical to a SP10 v3 except for the driver. I don’t know why the v3 was made though, since v2 was nicer. In particular, the tailcap has like a third as much surface area for tail-standing, so it falls over easily… and the button was downgraded. There’s also a 2-way clip which is pretty “meh” both ways instead of being good for at least one direction. The reverse-voltage protection makes my 14500 cells not work. And the LED seems green compared to others I use… but I’m pretty sensitive to that, and have been a bit spoiled by sw45k and tint-mix lights which are well below BBL.
However, the beam shape is nice, the CCT is fairly neutral and consistent, the host is lightweight and rugged, it’s the first AA-compatible Anduril light, it has reflashing pads, the driver seems pretty efficient, it goes smoothly from very low to very high (for an AA cell), it comes in pretty colors, and the price is really good. It’s a very practical item.
So… it’s not perfect. But as a budget AA light, it’s pretty good.
That’s awesome to hear, and what we can hope for from Sofirn. Good price, reflashing pads, decent build and beam shape. Throw an SW45K in there and call it a day.
Basically, i want to buy this driver. The host really misses so many points for me.
Get this driver in an FW1AA style light with a TIR and good clip… that’s the spot
That’s a negative outlook. When designing a product, if there is a market for it, why should anyone be the police to stop it from selling? Gas and lighters are sold right?
The product was designed a long time ago. The only part still changing is the firmware. Sofirn already confirmed it’s way too late to change anything else.
There may be some negative changes to this version, but it’s still awesome to finish this project after more than two years and get the first multi-chemistry flashlight with Anduril! If this is a success, Lumintop might be interested to get something competitive and makes a FWAA with a similar driver!
That gets political really quick.
There’s a market for bioweapons and chemical nerve agents 
I was just making a dumb joke. I didn’t mean anything. I’ve just seen the same guy in multiple threads going on about wanting every light to have USB charging no matter what. I thought it’d be funny to bust his balls a little.
I thought your post was hilarious
Me too. I laughed out loud. Hoping everyone can keep it good spirited yet have a little fun.
Heck, even I laughed! 
I appreciate good humour when I see it!
3 uA is very nice result! I am curious…if it is not a secret, how you measure? What equipment you use?
